The book examines the worth of arguments for and against theism, and the claim that there is a God. It covers the most important traditional arguments for the existence of God: the cosmological argument, arguments from design, from the occurrence of consciousness and moral awareness, and from the occurrence of miracles and religious experience; and also the argument from evil against theism. The author attempts to show that none of these arguments is deductively valid, but they almost all lend inductive support and the argument from evil has no force at all.
